US Patent and Trademark Office Grants Azbil BioVigilant’s Request

TUCSON, AZ – June 26, 2012 – Azbil BioVigilant, Inc., (www.biovigilant.com), inventors of Instantaneous Microbial Detection™, announced today that the US Patent and Trademark Office (USPTO) has granted the Company’s request for reexamination of a patent which is the subject of a lawsuit filed against Azbil BioVigilant by TSI, Inc. Specifically, the USPTO rejected all claims of TSI’s patent because multiple prior art references taught the claimed elements, including the use of a laser diode. In addition to its invalidity positions, Azbil BioVigilant maintains that it does not infringe the TSI patent. TSI failed in a prior litigation filed in Minnesota against Azbil BioVigilant on the same patent, voluntarily dismissing that action.

Representing Azbil BioVigilant in its patent litigation is Amster, Rothstein & Ebenstein LLP.
